So, you’ve probably seen the photo. It looks like a paved path. It looks like someone laid down bricks at the bottom of the Pacific Ocean. It looks like the way to Oz.
The internet, being the internet, went absolutely wild when the crew of the Exploration Vessel (E/V) Nautilus dropped footage of a "yellow brick road" on the summit of the Nootka Seamount. People started talking about Atlantis. They talked about ancient civilizations. Honestly, it’s easy to see why. The structure is weirdly geometric. It’s got these perfect 90-degree angles. It’s yellow. It looks intentional.
But it isn't.
Nature is just really good at geometry sometimes. What the researchers actually found back in 2022 while exploring the Liliʻuokalani Ridge National Marine Monument was a geological phenomenon that happens when you mix volcanic rock with a whole lot of pressure and some very specific temperature swings.
The Geology of the "Pavement"
The "deep sea yellow brick road" is actually a fractured flow of hyaloclastite rock.
Hyaloclastite is a type of volcanic rock. It forms during high-energy eruptions where basaltic rock fragments settle into the seabed. Basically, when a volcano erupts under thousands of feet of water, the cooling process isn't exactly subtle. The rock shrinks. It cracks. And because of the way physics works, those cracks often follow very straight, perpendicular lines.
Think about a dried-up lake bed in the desert. You’ve seen those hexagonal or rectangular patterns in the mud, right? This is the same basic principle, just at the bottom of the ocean and made of volcanic glass. The scientists on the Nautilus were actually giddy when they saw it, but not because they found a lost city. They were stoked because they were seeing a pristine example of "basaltic fracturing."
The yellow color? That’s not paint or gold. It’s just iron and manganese oxides that have leached out of the rock over millions of years. It’s rust, essentially. Really pretty, underwater rust.

Why the Discovery Matters (Even Without Aliens)
It’s easy to feel a little let down when "Atlantis" turns out to be "cracked rocks." But the reality is actually cooler. The Liliʻuokalani Ridge is part of the Papahānaumokuākea Marine National Monument, which is one of the largest marine conservation areas on the planet. Most of it has never been seen by human eyes.
The Nautilus team, led by the Ocean Exploration Trust, wasn't just looking for cool photos. They were studying the biodiversity of these underwater mountains. These seamounts act like islands in the desert. They provide a hard surface for corals and sponges to latch onto in a deep sea that is mostly just endless mud and silt.
When you look at that "road," you aren't looking at a path to a city. You're looking at a 1,000-meter-deep ecosystem.
Debunking the Myths
Let's get real for a second. Why do we want it to be a road?
Humans are hardwired to find patterns. It’s called apophenia. We see faces in clouds and roads in the abyss. But the deep sea is a harsh place for anything built by humans. At the depths where this "road" was found—roughly 3,000 meters down—the pressure is immense. Anything made of traditional brick and mortar would have been crushed or eroded long ago.
Moreover, the "bricks" aren't actually individual stones. If you look closely at the high-resolution 4K footage provided by the ROV Hercules, you can see that the cracks don't go all the way through. It's a single sheet of rock that has been "scored" by thermal stress. It’s one big piece of geological history masquerading as a walkway.
Exploring the Liliʻuokalani Ridge
The expedition that found the deep sea yellow brick road was part of a larger effort to understand the "seamount chains" of the Pacific. These chains are formed by hotspots—places where magma pushes through the Earth's crust as the tectonic plates move over them.

The Nootka Seamount is old. We’re talking millions of years.
During the dive, the team also spotted some incredible biology:
- Ghostly white sponges that look like something out of a sci-fi movie.
- Deep-sea sea cucumbers (sometimes called "sea pigs") scavenging the seafloor.
- Corals that have been growing for hundreds, maybe thousands, of years.
The "road" is just the stage. The life living on it is the actual show.
The Logistics of Deep Sea Exploration
How do we even find this stuff? It’s not like you can just go for a swim.
The E/V Nautilus uses Remotely Operated Vehicles (ROVs). These are massive, tethered robots equipped with high-definition cameras and robotic arms. They are piloted by people sitting in a control room on a ship miles above.
When the pilots saw the road, they were live-streaming. That’s why it went viral so fast. You can actually go back and watch the archives. You’ll hear the scientists' genuine surprise. One of them literally shouted, "It’s the road to Atlantis!" They were joking, of course, but that soundbite was all the internet needed to lose its mind.
What’s Next for the Nautilus?
The search doesn't stop at one weird rock formation. The Ocean Exploration Trust is constantly mapping new areas of the seafloor. As of 2026, we still have mapped less than 25% of the ocean floor at high resolution.

Every time they send an ROV down, they find something that defies expectation. Sometimes it's a "yellow brick road." Sometimes it's a species of octopus that looks like Dumbo. Sometimes it's a field of hydrothermal vents that shouldn't exist.
The importance of these missions is hard to overstate. We are currently in a race to understand the deep sea before deep-sea mining begins to strip these environments for minerals. Knowing that a "road" is actually a fragile volcanic ecosystem helps scientists argue for its protection.
How to Follow the Science
If you’re interested in this kind of stuff, don’t just settle for the memes. The real data is out there.
- Watch the Live Streams: The Nautilus Live website streams their dives in real-time. You can hear the scientists argue about geology as it happens.
- Check the NOAA Archives: The National Oceanic and Atmospheric Administration (NOAA) keeps massive databases of these dives.
- Support Marine Conservation: Areas like Papahānaumokuākea are under constant pressure from commercial interests.
The deep sea yellow brick road is a reminder that the Earth is still capable of surprising us. We don't need to invent lost civilizations to make the ocean interesting. The truth—that volcanoes can "pave" the seafloor through sheer physical force—is plenty cool on its own.
Practical Steps for Enthusiasts
If you want to stay updated on deep-sea discoveries without falling for the "clickbait" trap:
- Follow the Ocean Exploration Trust on social media for direct updates from the E/V Nautilus.
- Use the Global Multi-Resolution Topography (GMRT) synthesis tool to look at high-res maps of the seafloor yourself.
- Read the peer-reviewed papers coming out of the University of Hawaii, as their researchers are often the lead scientists on these Pacific expeditions.
The ocean is the last great frontier on Earth. It's weird, it's dark, and sometimes it looks like a fairy tale. Just remember that behind every "brick," there is a billion-year-old story of heat, pressure, and time.
